Assignment of seven genes to distinct intervals on the midportion of human chromosome 19q surrounding the myotonic dystrophy gene region

Abstract

Hybridization studies using a panel of somatic cell hybrids with subchromosomal segments of 19q have localized the genes encoding hormone-sensitive lipase (LIPE), carcinoembryonic antigen (CEA), and small nuclear ribonucleoprotein polypeptide A (SNRPA) to various regions of 19q13.1; the cellular receptor for poliovirus sensitivity (PVS) to 19ql3.2; and the genes coding for prostate-specific antigen (APS), human pancreatic kallikrein (KLK1), and small nuclear ribonucleoprotein 70-kD poly-peptide (SNRP70) to 19q 13.3 →qter. Our results exclude several of these genes from being seriously considered as a candidate for the myotonic dystrophy gene on 19q.
